Holotype species: Sodalinema komarekii Cellamare, Charlotte Duval, Touibi, Djediat & Cécile Bernard

Original publication and holotype designation: Cellamare, M., Duval, C., Drelin, Y., Djediat, C., Toibi, N., Agogué, H., Leboulanger, C., Ader, M. & Bernard, C. (2018). Characterization of phototrophic microorganisms and description of new cyanobacteria isolated from the saline-alkaline crater-lake Dziani Dzaha (Mayotte, Indian Ocean). FEMS Microbiology Ecology 94: 1-25, 17 figs, 3 tables.

Description: Thallus emerald green, diffluent, forming thin mats. Filaments solitary, nearly straight, flexuous, blue-green or yellow-green. Trichome cylindrical, slightly constricted at the crosswalls, very slightly attenuated at the ends, sometimes with a very fine, attached and diffluent sheath. Cells longer than wide, 2.4–3 µm wide. Cell content with a large refractive granule on either or both sides of the cross-walls. Apical cell rounded, hemispherical, often with a large granule (aerotope?). Motility present.

Most recent taxonomic treatment adopted: Strunecký, O., Ivanova, A.P. & Mares, J. (2022 '2023'). An updated classification of cyanobacterial orders and families based on phylogenomic and polyphasic analysis (Review). Journal of Phycology 59(1): 12-51.

Comments: Emeded description (emend. Samylina, Sinetova, Kupriyanova and Tourova): Thallus emerald green, diffluent, forming thin mats or freefloating filaments. Filaments solitary or parallel in bundles, nearly straight, flexuous, blue–green, pale blue–green or yellow– green. Trichomes motile, cylindrical, slightly constricted at the cross walls, slightly attenuated towards the ends, sheaths are absent or thin and colorless, containing only one trichome. Bundles of trichomes can be surrounded by amorphous, colorless slime. Cells cylindrical, isodiametric or elongated, (2.3)2.6–5.7 µm long and 2.0–4.6 µm wide. Cross-walls with 1–2 cyanophycin granules on either or both sides and/or with yellowish granulations with homogeneous or finely granular content. Apical cells rounded, hemispherical, sometimes with extrusions, often with a large polar gas vacuole. Thylakoid arrangement is parietal with a central fascicle, sometimes with spherical formations. Possess nifH genes of ‘desulfo’ type.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
